Type 1 diabetes (T1D) and sleep, or lack thereof, are often tied together. Someone living with T1D must navigate a wide range of challenges that can impact sleep, and poor quality of sleep negatively affects your psychological and physical health.
In addition, one of the greatest fears of nighttime is low blood sugar (called hypoglycemia), which occurs when blood-sugar levels fall below 70 mg/dL. Symptoms can include shaking, an accelerated heart rate, and clammy skin. It’s possible to sleep through a hypoglycemic event, but you can wake up tired, confused, sweaty, and can feel lethargic or foggy.
But artificial pancreas systems are changing that.
Artificial pancreas systems (also called automated insulin delivery systems) have two interrelated functions: Monitoring the blood-sugar levels in your body (through a continuous glucose monitor) and automatically providing insulin to keep them in a healthy range (through an insulin pump), via a smart algorithm. By automating much of blood-sugar management, these systems can help improve diabetes-related outcomes and lighten the burden of T1D.
Even during sleep.
Time-in-Range and Sleep
Time-in-range (TIR) is a measurement that tells you what percentage of the day your blood sugars are in your goal range (typically 70-180 mg/dl). The American Diabetes Association recommends that people with diabetes spend 70% of their time in the target range, meaning you should aim for roughly 17 out of 24 hours each day to be in range. Unfortunately, less than half of the diabetes population meets this recommendation.[i]
But experts emphasize that even a 5% improvement in TIR—let’s say, going from 60% to 65%—is meaningful, as it translates to one more hour per day spent in-range.[ii]
Now, let’s look at some recent scientific findings in the table below.
Not only can the artificial pancreas systems improve time-in-range, but they can dramatically improve time-in-range during sleep.

More time-in-range, even when you’re asleep. Now that’s research that can help you rest easy and more often than not, wake up on the right side of the bed.
Have a goodnight!

RX ONLY. The t:slim X2 insulin pump with Control-IQ technology is indicated for patients with type 1 diabetes, 6 years and older. BOXED WARNING: Control-IQ technology should not be used by people under age 6, or who use less than 10 units of insulin/day, or who weigh less than 55 lbs.
